Carey Trevon Thomas, of Arrow Bear, was taken into custody after Loma Linda Children’s Hospital reported the baby’s injuries to police, according to the San Bernardino County Sheriff-Coroner Department.

Thomas was being held at the Central Detention Center on $500,000 bail.

Investigators did not specify Thomas’ relationship to the victim.

The suspect used to volunteer at a kindergarten classroom at the Living Springs Christian School, which has since been closed.

Anyone with information was asked to call the Crimes Against Children Detail at (909) 387-3615.
